Magnifying glass over the map of Iran.

Iran’s Military Exercises, Nuclear Negotiations and the Regional Order

Between December 2024 and March 2025, Iran conducted one of its most robust military exercises in decades. Eqtedar (authority or power) and Zulfiqar (sword of revered fourth Islamic caliphate and Shi’ite first Imam, Ali bin Abu Talib) spanned multiple phases and involved both the Islamic Revolutionary Guard Corps (IRGC) and Artesh.[i] The exercises showcased new weapons and technology for Iran’s ground, naval and air defence forces alike. The military drills came at a time of extreme uncertainty for Iran after its ‘Axis of Resistance’ experienced catastrophic losses in the region, and as the US and Israel repeatedly threatened to strike its nuclear facilities.[ii]

2024 proved to be a watershed moment for Iran with regards to its influence over and strength in the region. Not only did Iran suffer from Israeli attacks on its soil, but the death of President Ebrahim Raisi and Foreign Minister Hossein Amirabdollahian in a helicopter crash, the fall of its proxy partners in Syria, Lebanon and Gaza, and multiple intelligence failures signalled the weakening of the regime on multiple fronts.

The first half of 2024 reiterated Iran’s position in the Middle East as the country responded to Israeli attacks on its embassy in Syria and conducted a transition of power after the elections. Notwithstanding, the second half of the year saw the assassination of the core leadership of its proxy network, including Hezbollah’s Hassan Nasrallah and Fuad Shukr, and Hamas’s Ismail Haniyeh and Yahya Sinwar. The Syrian debacle and the flight of Bashar al-Assad–Iran’s long-standing ally–in December 2024 proved to be the last nail in the coffin of a united ‘Axis of Resistance’.[iii] Initial military successes in the Gaza Strip, Lebanon and Syria emboldened Israel to carry out further attacks on Iranian sites.[iv] Furthermore, US president Donald Trump also suggested that bombing Iran could be on the table if it did not accept his conditions for a new nuclear deal.[v]

Military exercises and their outcome

Following the sudden erosion of its deterrence capabilities, Iran looked towards projecting power by showcasing its indigenous military might. As part of these drills, the unveiling of four types of weaponry was of particular importance: underground missile and naval sites, a drone carrier, new drone models, and its air defence capabilities.

Iran revealed multiple underground missile sites which they labelled as ‘missile cities’.[vi] These bases host a wide array of missiles including Khorramshahr-4, Jahad, Qadar, Emad, Kheibarshekan and others, with a range between 1,200 and 1,500 miles (2000 and 2500 km). Iran also showcased an underground naval base at an undisclosed location in the Persian Gulf.[vii] The existence of such sites reflects Iran’s advancements in the missile domain as well as its resolve to avoid making compromises in this sector, in contrast to what Trump had expected.[viii] Such a missile arsenal also positioned Iran to be ready for a prolonged conflict if the need arises.

Iran also unveiled a drone carrier named Shahid Bagheri in February 2025. Unlike traditional aircraft carriers, the drone carrier is an affordable, rapidly deployable and serves as an extension of Iran’s naval power. The operational range of this carrier is 22,000 miles (35,000 km), and it can reportedly stay on the seas without refuelling for up to a year.[ix] Iran’s capabilities to find alternatives to high-cost technology cannot be overlooked.

Unlike in previous years when Iran exerted pressure on commercial shipping lines and the US naval fleet in the Persian Gulf, limiting its operations to the Strait of Hormuz, the drone carrier could allow the country to reach the Arabian and Red seas, the Indian Ocean, and even the Pacific and Atlantic oceans. In 2021, an Iranian naval vessel already undertook a 4-month-long voyage to the Atlantic Ocean.[x]

Iran lined up a variety of drones, including the JAS-313, the UAV version of its Qaher-313 fifth generation stealth fighter jet. In January, the Iranian military received 1000 drones, significantly boosting its asymmetric power. Similarly, Iran unveiled its long-range Gaza drone with a reported range of 620 miles (1000 km) and a payload capacity of 500 kg.[xi] The JAS-313 is also claimed to have a high subsonic speed of 1000 km/h and flight endurance of one hour.[xii] Iran also displayed various other short-range drones, including Qandil, Raad and Redwan.

Finally, Iran paraded its Russian-built S-300 and indigenously developed Bavar-373 air defence systems. While it was common knowledge that Iran had purchased the S-300 and also developed its own air defence systems, the purpose of showcasing them aimed to disprove claims of their destruction in Israeli airstrikes in October 2024.[xiii] Although the S-300 is now equipped with advanced missiles, its capabilities are more limited in comparison to Iranian-built systems. Demonstrating this was the downing of an American Global Hawk drone with the mid-ranged Khordad air defence system.[xiv] Similarly, to overcome the limitations of the S-300, Iran has integrated Baver-373s into the system, utilizing batteries and launchers.[xv] The above provide Iran with a multi-layered air defence system.

What will Iran do after the attacks on its nuclear sites?

Beginning on 13th June, Israel conducted airstrikes in Iran, targeting nuclear sites and assassinating the regime’s top military brass. Iran retaliated by firing KheibarShekan, Khorramshahr, Sejjil and Fatah missiles, which successfully penetrated Israeli air defences and hit their targets.[xvi] Iran also targeted the Israeli military, in addition to technological, economic and energy infrastructure.[xvii] Joining in on the war, President Trump ordered US attacks on Fordow, Natanz and Esfahan on 21 June, using the US’s largest bunker busters for the first time.[xviii] Trump has claimed that Iran’s nuclear capabilities were completely destroyed as a result. On 23rd June, Iran responded to the unprecedented attacks on its soil with missile strikes on the US’s Al Udeid airbase in Qatar.

At the time of publication, a fragile ceasefire is in effect between Iran and Israel, apparently negotiated by President Trump, following Iran’s attacks on the Al Udeid base.

Iran has been hailed as the master of asymmetric warfare and proxy strategy. Its recent military exercises combined with the attacks on its soil might nonetheless indicate a shift in the regime’s military thinking. Based on previous reports, Ayatollah Ali Khamenei asked the defence apparatus to upgrade the reach of Iranian missiles–a move that was interpreted as Iran’s potential ambition to develop long range or even intercontinental ballistic missiles further.[xix] Similarly, Khamenei’s advisor and the former parliamentary speaker Ali Larijani also warned that in case of an attack, Iran might opt for nuclear weapons.[xx]

Despite President Trump’s claims of an overwhelming military success, it is unclear whether the regime managed to transport its enriched uranium stockpiles away from the primary sites attacked. The intelligence report also suggests that strikes on Iran’s nuclear sites did not dismantle its nuclear program.[xxi] In addition to this, even if such stockpiles have been destroyed, Iran’s know-how and, arguably, its determination to develop nuclear weapons cannot be fully eliminated. The Ayatollah’s hiding and the transition of the regime’s remaining leaders to non-digital means of communication suggest that Iran might opt for a level of secrecy and opaque operations never seen before. Leaving the proxy route behind, Iran might focus on developing military self-reliance and self-sufficiency with full steam.

The ceasefire notwithstanding, Iran might not return to the negotiating table either. While the counterstrike on the US base in Qatar was largely performative, it provided a semblance of retaliation in the eyes of the Iranian public. Agreeing to renewed negotiations with the US after the latter violated Iran’s sovereignty with its strikes would directly undermine this posture. Indirect negotiations (e.g. via Omani mediation) could still take place, but the US’s credibility as a party to the talks has mostly been undermined. In addition to this, military regrouping and rearmament could be pursued even in parallel with negotiations.

The latter point applies to Iran’s proxies too. The statement of Hezbollah’s secretary-general, Sheikh Naim Qassem, of supporting Iran against Israel could potentially be a signal of re-opening a front in the conflict at a later time.[xxii] Similarly, the Houthis of Yemen have threatened to attack US warships in the Red Sea.[xxiii]

Iran seems to be stepping into a new and uncertain chapter in its strategic thinking. With unprecedented attacks on its nuclear facilities, a weakening of its proxy network, and the emergence of advanced homegrown military technologies, it looks like Tehran is shifting away from depending on non-state actors. Instead, it is embracing a strategy focused on conventional deterrence and self-reliance in technology. The near future of the Middle East may not be dictated by diplomacy or efforts to ease tensions, but rather by displays of power and calculated defiance.
